I used this to cycle from Lands End to John O Groats in September 2012 and from Calais to the Mediterranean in May 2013. It stood up to rain, sleet, snow, and gales, as well as baking sunshine. The maps kept dry, the case kept secure (no flapping around at all), and it’s as good now as it was when I first bought it.
